underdash courtesy lights?

That doesn't look like mine. But not sure if mine is factory are not but I like having them. That looks more like the cig lighter and AC maybe. The wire on the left has the funny plug on the end for the cig lighter.
:chevy:

The one on the right is for the lighter. The one on the left looks like it's an extension to tap off of an existing power source. The courtesy light wiring is white and orange, as in Andy's picture.

...has a picture of the connector at the cig lighter. It is the only connector like it on our trucks that I know of.

The one on the left reminds me of the wire that plugs into the "CIG" terminal at the fuse box. It should plug into that terminal at the "Y" end (left connector at the "Y" in the photo). If the one in the right has that connector for the lighter, then I think the opposite end connects to the short leg of the "Y". It's been to long since I rewired my truck to be 100% positive. If the one on the left has the funky connector for the lighter then the one on the right should plug into the short leg of the "Y" and powers the blower relay.

Your left harness is for the cigarette lighter. The one on the right is for the radio. The connector on the right harness looks weird because it inserts into the factory speaker connector that plugs into the radio. Looks like they both are in good shape:metal:
